First Aid Measures

General Advice: Seek medical attention if symptoms occur or persist.
Inhalation: Move person to fresh air, monitor breathing; if symptoms appear, consult physician at once.
Skin Contact: Remove contaminated clothing, rinse affected skin thoroughly with soap and water, seek medical help for persistent reactions.
Eye Contact: Rinse eyes with gentle stream of water for at least 15 minutes, lift eyelids occasionally, get medical attention.
Ingestion: Rinse mouth, drink small quantity of water only if victim is conscious; avoid inducing vomiting, call for immediate medical support.

Fire-Fighting Measures

Suitable Extinguishing Media: Use foam, dry chemical powder, or carbon dioxide; avoid water jets as product may dissolve rapidly.
Hazards from Combustion: Decomposes under fire conditions into hydrochloric acid fumes, nitrogen oxides, carbon monoxide, and carbon dioxide.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Special Procedures: Cool intact containers near fire with water spray, avoid inhaling smoke or vapors.

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, wear chemical-resistant gloves, safety goggles, dust mask or respirator.
Environmental Precautions: Prevent runoff into sewers, drains, or open water; notify authorities if material contaminates public waterways.
Containment: Sweep or scoop up remaining material without generating dust, store in closed labeled drum for disposal.
Cleanup Methods: Wash spill area thoroughly with plenty of water, ventilate area, collect contaminated rinse water for approved disposal.

Handling and Storage

Handling: Use in well-ventilated settings, avoid generating dust, prevent direct contact with skin or eyes, provide appropriate ventilation.
Storage: Store container tightly closed in a dry, cool, well-ventilated area, protected from heat, moisture, and incompatible materials such as strong oxidizers.
Incompatibilities: Strong oxidizers, acids, and strong alkalis can react with quaternary ammonium compounds and should be stored separately.
Hygiene Measures: Wash hands after handling and before eating, smoking, or drinking; keep work clothes separate from household laundry.

Exposure Controls and Personal Protection

Engineering Controls: Work in chemical fume hood or well-ventilated area.
Personal Protection: Chemical-resistant gloves (nitrile, neoprene), safety goggles or face shield, lab coat or protective clothing, dust mask or respirator (N95 or greater) where exposure to dust occurs.
Exposure Limits: Not established through OSHA, NIOSH, or ACGIH, but limit exposure as with similar irritant chemicals.
Environmental Controls: Avoid discharge to environment, observe all federal, state, and local environmental regulations.

Polymerization: Does not undergo hazardous polymerization.

Toxicological Information

Routes of Exposure: Inhalation, ingestion, dermal, ocular
Acute Toxicity: Estimated LD50 (rat, oral): > 1000 mg/kg; low to moderate toxicity
Health Effects: Ingestion leads to gastrointestinal upset, nausea or vomiting; skin contact can cause irritation, prolonged exposure may cause dermatitis; eye contact results in irritation or redness; inhalation of dust triggers coughing or mild respiratory issues.
Chronic Exposure: No significant data on long-term effects; avoid repeated exposure to minimize risk
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Mutagenicity: Information not available
Reproductive Effects: Data insufficient; recommended to avoid exposure if pregnant or breastfeeding
Target Organs: Possible irritation to skin, eyes, and respiratory tract.

Ecological Information

Ecotoxicity: Harmful to aquatic organisms, especially in concentrated spills; high chemical oxygen demand.
Persistence and Degradability: Quaternary ammonium compounds persist in environment, may not fully biodegrade under natural conditions.
Bioaccumulation Potential: Moderate risk; can accumulate in aquatic organisms in contaminated waters.
Mobility in Soil: Highly soluble in water, easily moves through soil and water systems.
Other Adverse Effects: Large releases may disrupt local ecosystems; avoid uncontrolled discharge to waterways.

Disposal Considerations

Waste Disposal: Collect waste in well-labeled containers, minimize dust formation, dispose of as hazardous chemical waste using licensed waste disposal contractor.
Contaminated Packaging: Empty containers can retain product residue; treat as hazardous waste and remove label before recycling, if allowable.
Environmental Precautions: Do not discharge residue or rinsate into sewer systems or surface waters.
Methods of Disposal: Incinerate in approved facility or use chemical landfill in accordance with all local and national regulations.
